GENERAL DEscarrTTN chute. When the traveling carriage is inpredetermined positions this card retaining'mechanism 59 becomeseffective at the beginning of amachine operation, and remains thus untilnearl the end` of said operation. Attached to the card chute isa-plurality of receptacles for holding cards to be acted upon by themachine and lto receive those 55 cards which have been acted upon.

The. slip chute has a. plurality of compression rolls which hold theslips inserted therein securely against the platen roll, so that saidslips win .be outomaticauy fed by'soid platen? rou. 50

Convenientl `means for releasing the compression rolls. is supplied foruse when removing or inserting slips.

A tally roll mechanism has been ,devised for the traveling carriage,which may be used alone or-in conjunction with either the card chute korslip` DETAIL DEscBrP'rroN Adjustable card receptacle or chute Referringto Figs. 1 and..3, a pair of plates 4| and 42 are shaped to form a cardreceptacle or chute 43, which encircles a platen roll 44 journaled inarms 39 (Figs. 1 and 14), on a traveling carriage frame 45. The carriageframe 45 is slidably mounted on a machine case 46, which encloses themachine mechanism and is in turn supported by a machine base (not shown)The card chute 43 (Fig. 3) is supported by a pair of rods 41 and 48carried by a pair of carriage end plates 49 and 59 (Fig. 1) which arecarried by-the shaft of platen 44, and travel as a unit with thetraveling carriage. A pair of plates and 52, (Figs. 3 and 4), one ateach end of the card chute 43, also supported by the rods 41 and 48,have mounted thereon a plurality of rollers 53, arranged to rotatablysupport apair of ring gears 54 and 55 mounted concentric to thecircularportion of the card chute 43. The ring gears 54 and 55 areconnected by a. horizontal cross bar 56 which lies near the outersurface of the plate 42 and carries two stop studs 51 which extendthrough parallel slots 58 cut in the circular portion ofthe plate 42.Journaled in the plates 5| and 52 is a. shaft 59 which has securedthereto a pair of pinions 68 and 6| (Figs. 3 and 5), which meshrespectively with the ring gears 54 and 55. Pivoted on the right end ofthe shaft 59 is a locking pawl 62 (Fig. 4) having a tooth 63 whichisnormally held in engagement with the ring gear 55 by a spring V64.Secured to the left end of the shaft 59 is a knurled hand knob 65.Formed on the locking pawl 62 is a right-angled ngerpiece 66 whichfacilitates disengaging said locking pawl.

When it is desired to change the location of the stop studs 51, theoperator, by means of the flngerpiece 66, disengages the locking pawl 62from the ring gear 55 and rotates the knob 65 until the stop studs 51are properly located. The finger-piece 66 is then released and thelocking pawl 62 engages the gear 55'and retains the stop studs 51 intheir newly adjusted positions.

Card retaininameans justable arms 13 secured to ashaft 15 supported bythe card chute plate 42 and the carriage end plate 58.

Secured to the shaft 15 is a tension arm 16 (Fig. 6) which is adapted tocooperate with a stud 11 in a release lever 18 pivoted on the shaft 48.The 5 upper end of the lever 18 has a right-angled extension towhich isfastened a knob 19 (Figs. 1 and 4). A spring 80 (Fig. 6) is tensioned tourge the arm 16, shaft 15, and arms 13 counter-clock- I Wise, which inturn presses the card tension flngers\.61 against the inside surface ofthe card chute plate 42. i

When it is. desired to release the clamping fingers 61 (Fig. 6) by hand,to either remove or insert a card, the operator presses downward on theknob 19, rocking the lever 18 counter-'clockwise, thus causing the stud11 to rockthe arm 16, shaft 15, and arms 13 clockwise, thereby raisingsaid-fingers 61 away from the card or plate 42 as the case may be.

It is also desirable to automatically release the fingers 61 tofacilitate in the insertion and withdrawal of cards into and from thechute when the carriage is in certain tabulated positions, and to obtainthis result, there is secured to the shaft 15 a plurality of releasearms 8| (Figs. 3, 11 and 12), adapted to cooperate with a roundedextension 82 on a pitman.83 (Figs. 11 and 12). The arms 8| may 'vary innumber, depending upon the system being used with the machine, and thesearms 8| may be clamped to the shaft 15 in any desired positions. 'Ihepitman 83 (Fig. 12) is slotted near its upper end to embrace a shoulderscrew 84 fast in the machine case 46. The lower end of the pitman 83 is35 pivoted to a lever 85 which is, in turn, pivoted to the machine case46, and has an arm 86 adapted to cooperate with a roller 81 carried by adrive arm 88 securedto a main shaft 89 supported between two mainmachine frames (not here shown). A link 90 connects the arm 88 to thedriven member of a clutch, the driving member of said clutch beinggeared to an electric motor, neither of which is here shown.

With the parts in the positions shown in Fig. 12, the arm 8| and shaft15 are held so that the tension fingers 61 are away from the card chute,or a card,provided one is in the chute. Thus,

a card may be readily inserted in the chute if it is empty, and on theother hand, any card in the chute may be easily removed.

During operation of the machine the arm-88 voscillates through an angleof approximately degrees, the rst movement being counter-clockwise, -Theinitial movement of the arm 88 with- 55 draws the roller 81 from the arm86 of the lever 85 allowing the pitman 83 to move downward and the shaft15 to rotate counter-clockwise under tension of the spring 8|) (Fig. 6).This y causes the `ingers 61 (Fig. 3) to be firmly pressed 60 againstany card located within the chute 43.

Tabulating release Zever atzd starting bar locking mechanism" Convenientmeans for releasing the traveling carriage for tabulation have beensupplied in the machine of the present invention, and will now bedescribed.

Referring to Figs. 1 and 13, a touchbar 9| is secured to a tabulatingrelease bar 92 slidably 70 mounted on a tabulating stop bar 93 by meansof a plurality of diagonal slots embracing a plurality of studs 94secured in said stop bar 93, which isin turnsecured to the travelingcarriage frame 45. The lower edge of the release 76 The right end ofthe'lever 98 is arranged to cooperate with a slot 99 in an automatictabulating lever |00 (Figs. 2 and 13) which is pivoted to the rightmachine frame (not shown).

Pivoted to a stud |0| in the lever |00 (Fig. 2) is a link |02 having aslot through which extends a stud |03 in a locking lever |04 pivoted tothe right machine frame (not shown). A spring |05 is stretched betweenthe studs |0| and |03 to form a flexible connection between the levers|00 and |04. The lever |04 has a notch |06 adapted-to cooperate with asquare stud |01 in a starting lever |08 pivoted at |09 to the rightmachine frame (not shown). One leg of a starting bar ||0 is pivoted tothe lever |08 so that depression of the starting bar 0 rocks the lever|08 counter-clockwise to release the machine for operation in the wellknown manner.

Depression of the touch bar 9| (Figs. 2 and 13) moves the plunger 95downward out of the path i ofthe tabulating stops 96, which allows thetraveling carriage to'be moved freely in either. direction. The downwardmovement of the plunger 95 rocks the levers 98, |00 and |04 clockwise,causing the notch |06 to move into the path of the stud |01 to preventdepression of the starting'bar ||0 as long as the touch bar 9| remainsdepressed.

Release of the machine for operation causes Y the stud |01 (Fig. 2) tomove upwardly to a podepress the touchbar 9| after the machine hasA beenreleased by depression of the motor bar ||0. Card storage means Cardstorage means have been provided for holding cards in convenientrelationship to'the card chute. Such card holders will now be ybrieflydescribed.` Referring to Fig. 1, attached to the machine case 46 4arecard holders I and ||2.

`The card holder lis arranged to hold cards preparatory to being runthrough the machine, and

'the holder |2 is arranged to receive those which have been acted uponby the machine. The card holders shown are for a particular system. Thesize and shape of the card holders as well as the number may be variedto meet the needs vof the systemv at hand.

Slip receptacle or. chute The traveling carriage of the instant machineis equipped with a. .slip receptacle or chute I8 (Figs. 1 and 7) which,as previously stated, may be used alone or in conjunction with the cardchute 43. A detailed description of the slip chute will now be given.

Fig. 1 well shows the location of the card and` for the insertion ofslips therebetween.

|29 and collars |32 respectively, and therefore slip chutes upon thetraveling carriage and their positions in relation to each other, whileFigs.

7 and 8 illustrate in detail the construction of the slip chute.

Referring to Fig. '1, the slip chute ||8 includes.' 5

a pair of end plates I3 and ||4 supported by the rods 41 and 48. Rods||6 and ||1 and two shafts |20 and |2| extend the width of theslip chuteand connect the plates |13 and ||4. A guide .plate `|22.(Figs. 7 arid 8)is secured tol the rod ||6 and is supported by the rods ||1 and 48. Theguide plate |22 is formed around the platen roll 44; ample clearancebeing allowed between the guide plate and platen .roll

The 1 guide plate |22 is supported at itsfront end by projections |23thereon bent around the rod 41. 'I'he guide plate |22 has therein aplurality of openings |24 through which the printing type lmakes contactwith the slip. 2

Hinged to the`rod 41 and straddling one of the projections |23 is acover |25 (Fig. 7) .which may be used .to hide from View matter printedin one of the columns on the slip. Also hinged on the rod 41 between thecover |25 and another of the' projections 23 is va.l cover |26 havingtherein a slot |21. When the cover |26 is in place over one of theopenings |24 only the matter on the printing line is visible through theslot |21. Farther along in this specification an 3 outline of a systemwill be given in which these covers yare used to advantage.v

'I'he shaft 20 (Fig. '7) .has secured thereonA a pair of adjustabletension collars |28, each having therein a hole into which is insertedone 3 end of a pair of springs |29. The other end of each spring |29 isinserted in a hole in each of a pair of tension arms |30. The arms|30-each have secured thereto a hub |3| by means of which said arms arepivoted on the shaft |20. 4 The hubs |3| are each partly cut away ontheir /face to form a step, which is adapted to co- Loperate with likesteps cut in adjustable release .having pivoted vthereon a plurality ofcompression rolls |34 held in position by clips |39. A release arm |35secured to the right end of the shaft |20 carries a stud |36 which isadapted 5 to cooperate with a cam slot |31 in a release lever |38pivoted on the rod 48. `The shaft |2| lis similar to the shaft |20 andcarries two tension arms |40 each having a stepped hub |4|, two tensioncollars |42, two 5 tension springs |43, and two stepped release collars|44. The arms |40, hubs |4|, collars |42, springs |43 and collars |44are identical With the arms |30, hubs |3"|,-'collars |28, springs onlyone of each of the former elements is shown in Fig. 7. The arms |40support a shaft |45 carrying tension rolls |46 held in place by clips|39. Also secured to the righta end of the shaft |2| is a. release arm|50 carrying a stud |5| vadapted to cooperate with a cam slot |52 in therelease lever 38.

The steps on the hubs |3|. and |4| and the steps on the collars |32 and|44 are cut off` center to allow the arms |30 and |40 to be moved 70 beurged toward the platen roll 44, thereby 75 firmly holding the slipinserted between said rolls and platen so that feeding of said slip willbe eifected by rotating the platen roll.

When removing a slip from the chute or when placing a new slip withinthe chute it becomes necessary to move the rolls |34 and |46 'away fromthe platen. This is accomplished by moving the lever |38 clockwise,which causes the cam slots |31 and |52 to coact with the studs |36and,|5| to rock the arm |35 and'shaft |20 clockwise, and the arm |50 andshaft |2| counter-clockwise. This causes the steps on the collars |32and |44 to engage the steps on the hubs |3| and |4| to rock the rolls|34 and |46 away from the platen roll 44. The shaft 15 extends throughand is .supported by the plates 3 and ||4.- The tension arms |40 haveclearance holes therein, so that the shaft 15 may pass through themwithout interference.

Tally roll mechanism A novel tally roll mechanism has been designed foruse on the traveling carriage ofthe Wellknown Ellis type accountingmachine. This tally roll may be used in conjunction with either the cardchute or slip chute previously described herein, or if desired, it maybe used alone. There are also numerous other ways in which such a tallyroll may be used to advantage. A detailed description of the tally rollmechanism follows.

Referring to Figs. 14, 15 and 16, a pair of main plates |53 and |54 aresecured to and supported by the rods 41 and 48. A supply roll |55 havinga wood core |56 is rotatably mounted between the plates |53 and |54. Ashouldered stud |51 secured in the plate |54 engagesa hole in the core|56 to support the right-hand end of the roll |55. The plate |53 carriesa spring plunger |58 which supports the left end of the roll |55, andlikewise supplies means for removing and installing supply rolls. Theplunger |58 also serves as a tension device to prevent the roll |55 fromrunning ahead of the tally roll feeding mechanism, to be hereinafterdescribed.

The paper from the supply roll |55 is first threaded about a roller |59(Fig. 16) carried by the rod 48, then around the kplaten roll 44. Fromthe platen 44 the paper pa'sses over a roller |60 carried by the rod 41,and'is then attached to a receiving roll |6| by being threaded through aslot |62 cut therein. The receiving roll |6| is journaled between theplates |53 and |54.

Secured to the left end of the receiving roll is a shaft |63 (Fig. 14)having its left end journaled in the carriage end-plate 48. A pinion |64(Fig.

15) fast to the shaft |63 meshes with an inter.

mediate pinion |65 mounted on an arm |66 piv- .Voted on the shaft |63. Astud |61 secured in the arm |66 is adapted to cooperate with a camsurforioff position. Secured t face |68 on an On-and-Oi lever |10pivoted on the plate 49. A spring |1I stretched between the plate |66and the lever |10 is tensioned to hold the stud |61 against the camsurface |68, andl also to retain the lever |/10 in either its on theleft end of the platen roll-44 is a gear |12 dapted to cooperate withthe pinion |65. l

With the lever |10 in the/'i position shown in Fig. 15, the pinion |65is meshed with the gear |12. The clockwise movement of the platen roll-44 caused by either the automatic or hand-feeding mechanism, through thepinions |64 and |65, revolve the receiving roll |61 (Fig. 16) in aclockwise direction, causing the tally paper to be wound thereon'.` Asboth` the automatic and paper used in certain transactions be preserved-10V as a matter of record or reference, and to that end a tally paperknife |14 (Figs. 14 and 16) has been conveniently located in relation tothe receiving roll |6| for the purpose of severing the above .mentionedportions when desired. .The l5 knife |14 is secured between the plates|53 and M odifed form of card receptacle or chute A modied form of cardreceptacle orchute 20 l is well illustrated in Figs. y17, 18 and 19.This card chute is similar in many respects to the preferred form of'card chute described earlier in this specification. Especially is thistrue regarding the means for securing or holding material 25 inserted insaid card chute and the means for automatically releasing the securingmeans. However, in the modified form of hand means for releasing thesecuring means is not shown, but if desired, may be incorporatedtherein.

'I he modified form of card chute (Fig. 17) composed of a main plate 15and an auxiliary plate |16, formed around the platen roll 44, issupported by the rods 41 and 48. The receiving end of the card chute isiiared to facilitate the in- 35 sertion of cards therein. The plate |15has an opening |11 through which the printing type makes contact with acard inserted in the card chute. Where the modified form of card chutediffers materially from the preferred form, is in 40 the stop mechanismfor locatingcards in proper relation to the printing type. This stopmechanism will now be explained.

The card chute plate |15 has near its center a.

slot through which 'extends' a pair of headed 45- lss carried by the pme|15. The noms las are 5,5 I

arranged in two parallel rows running lengthwise Y of th te |15. Thestuds |83 and |84 are of such len h that they protrude within the chuteand form a stop for locating cards inserted withinsaid chute. '60

When it is desired to change the location of the stop studs the operatorgrasps the two protruding ends of the stop bar |82, springing themoutward until the stop studs |83 and |84 are disengaged v from the holes|85 and clear of the chute plate 6 |15. The stop bar may then be moved,guided by the slot |80 and studs |8I until the stop studs |83 and |84are located over the desired set of holes. Releasing the ends of the bar|82 causes the stop studs |83 and |84 to be properly positioned by en-70 tering the selected set of holes |85.`

Statement of operation As an example of operation letus take the case ofa telephone company in a large city having a 75 each operation.

great number of subscribers. The system used by this company requiresthat its subscribers 'pay' a at rate for a certain number of calls, say75, and 5 cents per call for all over 75 calls. Each subscribers phonehas a register or step-by-step counter located at the central oiiice orexchange, which accumulates 1 each time the subscriber makes a call.These registers-each have an identiflcation number, which is generallythe same as that of the telephone they represent.

In the system used by this particular company, a permanent record iskept of each subscribers account upon a Ledger Card |86 (Figs. 1 and 9).This ledger card is divided into spaces representing twenty-four monthlyperiods, and contains the name of the central ofiice, the telephone orregister number of the subscriber, and the minimum number of callsallowed by his contract without extra charge. The monthly calculation ofeach subscribers account takes place upon a Work Sheet |81 (Figs. 1andAlO), which is arranged to take care of the monthly statements of 100subscribers who are listed numerically by telephone or register numberin a column headed Telephone or Register Number.

At a fixed time each month a reading isA taken of the telephoneregisters by photographing them in blocks of 100. Prints of thesephotographs are turned over to the machine operators for the purpose ofcopying the register readings 'upon the Work Sheet, which isaccomplished thus:

The operator releases the slip chute compres'- sion rolls |34 and |46(Fig. 1) by moving the lever |38 clockwise. The Work Sheet representingthe register numbers 3800 to 3899is then inserted in the slip chute,adjusted until the line bearing the first register number is in linewith the printing type, and then clamped in position by releasing thelever |38. v'I'he operator then raises the cover |25, which previouslyobscured the column headed Present Reading, and copies therein theregister readings taken from the photographic print of the registers3800 to 3899 inclusive. The machine is arranged to automatically feedthe Work Sheet in the usual manner, from line line near the end of Afterhaving copied all the register readings, the operator in a clearingoperation prints the total thereof at the foot of the Present Readingcolumn. The cover |25 is then closed, the

cover |26 raised, the Work Sheet returned to the starting position, andthe: traveling carriage tabulated until the column headed Proof Readingis in horizontal alinement with the printing type. In this column theoperator again copies the register readings from the photographic printand takes a total thereof, the same as before. This total is comparedwith the Vprevious total for the purpose of detecting errors in thecopying'of the register reading.-

Next the operator places the Ledger Cards |86 for the register numbers3800 to 3899 in the holder` in sequentialorder. ,The card for theregister number3800 is placed in the card chutel;

the `computation of each account The operator then proceeds with thecomputation of that.

particular account.

Wheniinished with one account the Work Sheet is automatically fed upwardto the next 5 line bearing the 4register number 3801. The Ledgerl Cardfor 3800 is placed in the receptacle |2 and the Ledger Card for 3801 isinserted in lthe card chute 43, and so on until the Ledger column headedRegister Reading on the Ledger'Card is in printing position. The presentl5 register reading of 655 for the number 3809 for the month of August,found on the Work Sheet is read by the operator, set up on the keyboard,and such amount isthen added into the totalizer and simultaneouslyprinted upon the Ledger 20 Card in the Register Reading column. Thecarriage is then tabulatedy to a column on the Worksheet under the titleof Previous Reading, and here the previous monthly reading of 560, foundon the Ledger Card is subtracted 25 from the present reading 'of 655 andsimultaneously printed upon the Work Sheet. The carriage is nexttabulated to a Gross Usage column on the Work Sheet, where in asub-total operation the difference between the present and 30 previousmonthly readings is printed upon the Work Sheet.

Since the minimum calls allowed by this contract has been exceeded, itisA necessary for the operator in a non-print operation to subtract the35 minimum number 75 from-the gross usage of 95. 'I'he carriage is thenreturned to a column on the Ledger Card headed Gross or AdditionalCalls,- and in a totalizing operation the difference between 75 and 95(20) is printed upon the 40 Ledger Card. The cost of the additionalcalls,

n which in this case is one dollar, is obtained from va chart andentered by hand in an Amount Column on the Ledger Card.

When the minimum number of calls (75) al- 45 lowed by this contract hasnot been exceeded, this fact will be manifest to the operator ,when thegross number of calls is printed in the Gross Usage column-on the WorkSheet.` In such talizing operation the gross number of ca lls is printedupon said Ledger Card. It @easily be seen how the tally roll mechanismexplained earlier herein could be substituted for the slip chutemechanism used in 60 the system outlined above, or in any similar case.It is also\possible to use the modified form of i card chute in anyinstance where the preferred form can be used.

The column headed Reg. No. on the Ledger 65 Card is used only when it isnecessary to remove the subscribers regular register in the centraloiilce for repairs or other reasons, at which time a substitute registeris used bearing a different number. In such event the operator writesthe 70 substitute register number in the Reg No. column.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to bei understood75 that it is not intended to confine the invention to the one form orembodiment herein disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow.
